Torymus macrurus (Foerster 1859).
Species not recognized
Foerster evidently described the female from a single specimen. He stated "Diese Art lebt in grossen fleischigen Gallen von Quercus pedunculata; ich erhielt sie ebenfalls aus dem Kaiserlichen Museo durch Herrn Kollar zur Ansicht; sie stammt aus Ungarn". We could not find any material in Naturhistorisches Museum, Vienna, in 1993. Erdös (1960) mentioned that there was no material in Budapest.
Fresh material reared in Poland and attributed to this species shows that it is very closely related to cyaneus.
